我们将并行和相控阵MRI的信息丰富的测量数据转换为相应的单线圈扫描仪可以获取的更嘈杂的数据。具体地说，我们用线性组合替换来自多个接收器的响应，该线性组合仅模拟来自单个聚合接收器的响应，充满了任何一个原始接收器的低信噪比和相位问题(然而，合并多个接收器是必要的，因为原始接收器通常具有有限的空间灵敏度)。这使得在开发针对多个接收器线圈的全部复杂性的算法之前，能够在单线圈扫描仪的更简单的环境中进行实验。
We convert the information-rich measurements of parallel and phased-array MRI into noisier data that a corresponding single-coil scanner could have taken. Specifically, we replace the responses from multiple receivers with a linear combination that emulates the response from only a single, aggregate receiver, replete with the low signal-to-noise ratio and phase problems of any single one of the original receivers (combining several receivers is necessary, however, since the original receivers usually have limited spatial sensitivity). This enables experimentation in the simpler context of a single-coil scanner prior to development of algorithms for the full complexity of multiple receiver coils.
